In arXiv:1012.5099, section III, the authors describe a supersymmetric extension to the standard model in which there is no Higgs sector at all, in the conventional sense. The up-type Higgs is a slepton in a mirror generation, and other masses come from "wrong Higgs" couplings to this particle. I'm wondering if this approach can revive the fortunes of N=2 supersymmetric extensions of the standard model, where there are three mirror generations, but which run into trouble with oblique electroweak corrections.

I realize that this may be, not just a research-level question, but a question which will require original research to answer! However, if anyone has an immediately decisive argument about the viability of such a theory, now's your chance. :-)
